I'm surprised one of the more experienced members have not chimed in on this, but those numbers seem from what I've read here pretty typical (maybe a little low) for the age and miles. If you do a search on the forum you will find lots of threads on this.

Here is just one recent one that had a little better numbers with some details about your intended use to know how it will do for you

Hx The meaning of this number is not fully understood but it appears to be inversely related to the battery internal resistance. As the internal resistance of the battery pack increases it is thought this percentage decreases. As internal resistance increases more energy is lost within the pack and the pack heats up more under load.

It's been my theory that Hx - at least before the 40kwh pack - represents a momentary "snapshot" of the same value that SOH represents, with the SOH being a longer term average. Maybe, maybe not. The Hx number for the 40kwh pack seems more disconnected from the SOH, at least while the packs are new.
